Battle Cats Wiki

Rotten Refuge is the twentieth stage in Island of Hidden Treasure.


  • 1 Coffin Zoge spawns after 3.33 seconds100f.
  • Infinite Thrillerz spawn after 3.33 seconds100f, delay 10~16.67 seconds300f~500f.
  • When the base reaches 99% HP:


If available, Jellycat can provide massive help, as he can be used against the first few enemies with no risk of him ever getting past Coffin Zoge. He'll allow players to build up a full wallet and max level Worker Cat before the start of the fight, which drastically reduces the battle's difficulty. Past that, his damage can provide massive help, especially dealing heavy damage to any Li'l Zyclone that he intercepts.

If one does not have Jellycat, another effective way to stall for money at the start is to immediately send out a Manic Eraser Cat and a Thaumaturge Cat when the stage begins. The two cats will make The Thrillerz use their two burrows, even when they are stuck attacking the Coffin Zoge. When The Thrillerz unburrow for the second time and are running towards your base, send Sifu Cat to kill them. If Sifu is at a high enough level, one Sifu will kill one of The Thrillerz and die to the next. As you slowly send Sifus, upgrade your Worker Cat and build money up.

The Holy Blast Cannon is highly recommended, as allowing the second Cadaver Bear to burrow can prove rather problematic.

Lastly, a high-level Sifu is one of the best ways to properly stall the aforementioned bears, so bringing him along, especially with Combos to improve its performance, is also highly recommended, unless below level 35-40, at which point the use of cheap meatshields becomes preferable.

Another strategy is one that requires a bit of timing and a bit of luck. Using Zamboney Cat and Healer Cat CC's synergy in the same way used to cheese Heavenly Tower stages and Flow Like the Stream, you can stall The Thrillerz and build up the enemy limit. After that, all you need to do is spawn Awakened Bahamut Cat and claim a victory.
